Husband left at the end of January as he has another woman. We have a 4yo DD and he wants to do 50% of the childcare which he is doing and we are managing to keep things amicable for DD's sake although I am very hurt and angry. Whilst acknowledging this he seems to think we can carry on as friends and sometimes do things as a family. Obviously DD would love this, she wanted a 'group hug' the other day which we weren't able to give her :( I want the best for DD and for her to be happy but I also think that he can't expect to play happy families when it suits him so am I being petty to not join his activities with DD or invite him to join us on our activities? I also feel that I don't want him to feel he can come to me for companionship but sometimes it is a fine line between being amicable for DD's sake whilst sharing information relevant to her care and being friendly and chatty generally.
